BICYCLE-SUPPORT.

SPECIFICATION formine; part of Letters Patent NO. 644,863, dated March 6, 1900.

Application filed December 13,1898. Sarial No. 699,130. (No modal.)

T aZZ w7o0m it mayconcern:

Be it known that I, CARL KORDENAT, a cit-i zen of the United States, and a resident of Reedsburg, in the oounty of Sauk and State of WVisconsin, have invented certain new and useful Improvements in Bicycle-Supports; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention has for its object to provide light, simple, and economical bicycle attachments capable of ready application to be normally out of the way, but which serve at option of riders as means for supporting the bicycles in upright position when not in use.

Therefore said invention consists in certain peculiarities of construction and combination of parts hereinafter particularly set forth with reference to the accompanyingdrawingsand subsequently claimed.

Figure 1 of the drawings represents a side elevation of a portion of a bicycle-frame provided with an attachment in accordance with my invention, the movable partof said attachment being swung down to working p0- sition; Fig. 2, a rcar view of said frame provided with iwo attachments in accordance with my invention, the movable part of one beng swung clown; Fig. 3, a detail plan view, partly in horizontal section, on the plane indioated by line 3 3 in the preceding figure; Fig. 4, a detail rear elevation, partly in section; Figs. 5,6, and 7, perspective views illustrating elements of the aforesaid attavhment; and Fig. 8 adetail plan view, partly in horizontal section, on the plane indicated byline 8 8 in the second figure of the series.

Referring by letter to the drawings, A represents a bracket made to fit a rear-f0rk brace B of a bicycle-frame, the lower end of this bracket being in the form of an outwardlyoffsetdisk b, having a countersunk central aperture, the outer face of this disk being provided with a plurality of depressions, herein shown in the form of radial grooves. The bracket A is also provided with apertured ears 0 in pairs at differentelevations, and extending through each pair of ears are the screw-threaded onde of a clip 0, engaged by olamp-nuts, that are tightened to fasten said bracket on the aforesaid rear-fork brace of a bicycle-frame.

Extcnding through the central aperture of the bracket-disk 6 is a bolt D, having its head in contact with a metal washer e, facing a rubber or other spring washerf, these washers loeing- Within the eountersink of said bracket-disk, isolated from dirt and moisture.

Bolt D constitutes a pivot for the offset disk end 9 of a swing-arm E, the angle of offset being the same as that of the bracket-disk b aboVe specified. As herein shown, an inner face-plate F is riveted to the disk end of the swing-arm, although it may be otherwise fasten ed in place, and this face-plate is provided with a projection such as the radial rib 71. for engagement with the depressions in the opposing outer side of the bracket-disk b aforesaLid, a nut i being run on the pivot-boltD against said disk end of the swing-arm.

The swing-arm approximates the length of the rear-fork brace of the bicycle-frame and is provided with upper spring-earsj for automatic clamping contact with said brace. As herein shown, the swing-arm may be made to simulate the outward appearance of the rean fork brace to which it is connected.

One radial depression 76 in the offset disk end of bracket Ais shown alined with the rear-fork brace 130 which said bracket is clamped, and when the arm E is swung up the projection t, constituting an integral part of said arm or of a face-plate made fast to the disk end of same, engages with the aforesaid depression to assist in retentionof the aforesaid arm in elevated position out of use. The springavasher abovc specified permits sufficient play of the arm E on the pivot-bolt D to provide for engagement of the projection h with depression k above specified or its disengagement therefrom. The other radial depressions m shown in the ofiset disk end of bracket A are so disposed that said bracket may be made to serve on either rear-fork' brace of a bicycle-frame, the projection h of the arm E being engaged with the proper one of these latter depressions when said arm is swung down to stand at an acute angle to said brace and serve as a support for holding the bicycle in upright position out of use. It is obvious that the swing-arm may be provided with the depressions and the projection ar ranged upon the disk end of the bracket, this being a more reversal of what is herein shown.

In Fig. 2 I show that each of the two rearfor]: braces of a bicycle-frame may be provided With an attachment similar to that hercin particularly shown and described.

Having thns described my nvention,what I daim as new, and desire to secure by Letters Patent, is

A bicycle-support com p1isng a bracket a1;- tachable t0 a rear-fork bra ee of a bicycle and having its 1ower and in the form of en ontwardly-offset disk provided Wibh a conntersunk central aperture, a spring-washer 1ocated in the oountersink of the dsk-apertnre isolated from di1t and moisturc, a pivot-bolt having the head thereof wiohin said disk-apercure in opposition to the spring-waLsher, an arm having one end thereof in the form of an apertnred disk loose on the pivot-bolb, a nut run on said pivot-bolt against ohe latter disk, and a radial projection on one of said disks engageable With any one of a plurality of radial deprcssions in the opposing disk, these depressions being so disposcd that said arm may be locked in clevated position parallel to the fork-brace or in swung-down position as a support for the bicycle at an acntc angle to said brace.

In testimony that I daim the foregoing I have herennto set my hand, at Reedsburg, in the county of Sank and State of Winconsin, in the presence of two witnesses.

CARL KORDENAT.
